south east, south africa's modern spiritual feelings, and find out what the trade is all about. 77 percent. 60 minutes dw. very want to know what makes the getting to the gym. loved yeah. and binding thing, step away from the spot. i'm not even allowed to go to my own car and everyone was later holes in every single day stuff getting you ready to meet the gym and then join me, right. just do it on dw, the should we wipe out own most gets those. i know the sometimes really annoying, but hey, i tell you,

they have some benefits for the environment more on that later. hi and welcome and sandra tree. nobody else. i'm happy to help you with us for a fresh episode of equal offer. hi, sandra. hi, everyone. i am present looms in legal side to area and together with my lovely co host, i'm happy to bring it to they show. stay tuned because we have some exciting stories for you coming up. why block chain this blaine, a rolling conservation in some get awesome and could be made quite frankly. and how of fun gas paint can you can help to get read off the basic plan. let's start off in some viet today, a country that depends very much on the culture, forest, and wide life. these results has been lost at a rapid pace from us are facing great difficulties in diversified the crops and

adapted to hoshal weather conditions. now one of the most pressing challenges the facing is also a lot of access to affordable loans to try out different things with venture to the sucka to explore potential solutions as well to be some far as subsidies with the digital world starts helping the suckers some yeah, he's using technology to benefit farmers in nature. this is the team behind putting a phone opposite to naples from us to both save money on ground loops with the at small groups of farmers creates a so called savings of members of a circle agree a fixed amount which they then each deposit every month. members can then either draw or lose from this money pool or earn interest on this savings. many farmers here face considerable challenges. they need money to fund solutions. in zambia,

almost $300000.00 hector is a forest need every year for chaco timber. and i've the culture on my colleague and i x and email that way, i like to say discussing them, but talk to us convey about time. so those are some form of trunk and most people couldn't from, and it's very important to, you know, cutting down of trees if they don't cutting down trees to mix up within one thing to do that. okay. how about the keeping? the team suggested small hold is produced rule honey, which they would then buy package and we sell in supermarkets, gm economic assemble on his team provide free be keeping workshops grants in the farm as an alternative, defalco production, the bees bring the benefits to for the we for example, costs for the nation and the fluids, the in the product to of what if you are growing in your,

from without the food to trees that you of good with that to him, it towards the way that they had. it's amaze, it's a sunflower. the new you said, benefit you to both of you. philip zulu is a small scale, meas, pharma. she has diversified in to be keeping them fish farming, making him far less vulnerable to dropped half of his family and is now indigenous forest. ideal for bees to forage be has the expensive for 20 heis zulu, needed the equivalent of $500.00 units and the amount which you would now be able to go through the pulling savings. so many farmers don't have bank accounts. it's easier for really because he doesn't to access, he has to produce enough often document for collection and guy is getting it on from the people that just stays within the community. and they know him. yeah. so, and that's where you and the interest rates as no, that's the, that's the reason get to me alone. because um,

it's kind of to in the savings circle. farmers can agree on their own interest rates. these are typically about 5 to 10 percent, which is a far cry from the 15 to 100 percent interest often demanded by informal money lenders. jenny cutnam can someone whose team hope the platform will in pa, farmers to invest in bigger collaborate the project. if they've got from, you know, like piece, no, it's given an opportunity for farmers once they've put their money together, maybe they will might say $10.00. so can, i'm going to enjoy a bowl into an indignation where they just happen to be, if from where they produce different products of that. and then from there it's become so, so you know, it's a stable income for them which action, but that's been, they me to get face of climate change is phillips who is eager to trial. the system with the new app calling isn't a test face until the end of 2023 farmers hope it will enable them to diversify and

expand this small holdings for the village of banking systems, london mobile. i think it would be helpful because people to see them money and security issues people can borrow without the the signing of the contract. the agreements as long as your balance is tiring. the pulling up is built with block chain technology, a digital system that allows people to transfer money without the need for traditional banks. all transactions on the platform recorded. janica, nec assemble, see studies mostly involved in the business. she says a generation is embracing new technologies to solve urgent issues. things um, you may have seen really the garage warranty gradation. like when you're growing up, you know, it was, i had to force me on my place and you go there and there is nothing anymore. so this is something that we're passionate about. and it's something that we also page

opportunities from to advocate see to social enterprises just like we are doing. polling should be available for farmers in 2024. in the meantime, janica noncustodial is working with 2000 be keepers. the stotts up has already sold, set the tons of honey in supermarkets, the sweet, sweet and tall farmers. i'm project based on forest at the same time. so let's talk about the health of plants now. well, often can because i use to get rid of diseases and to get better yields. no such a great idea for the environment because just like that it can be bodily damaged. well, the other ways on the age of kenya is only survived the punch of tropical rain forest, a fungal wait for an is being developed. and the seems to be a sit on the, on the vibratory and a role model for other countries to help in,

in natural ways. these flowers grow well in can you to well, in fact strike go purple, which we might be pretty, but it's devastating to crumbs it viruses and dry soil and poses a serious threat to harvest as a grownup must adult as can boil, explain if that part of the take when i know it's kind of caused some damage to epsilon, to pass in in the fall. as you can see this move if this tented, by the time you have seen, let's try to imagine the destruction these sort of ended then. because the say the cds on the ground, the parasitic plot attaches itself to the roots of crops and then extract nutrients from them at their expense. they start to wield while the we'd flourishes. margaret key, so nose the problem all too well, which we'd regularly decimate her mace and milledgeville for you. oh hi,

ongoing issue out to some well, we've been struggling with the problem of which weed for many years. so we tried crops, but the yield was a no good school follow. well, we tried to stop it spreading by sweeping. i'm dead brain and the animal waste woman and distributing it in the field, but it doesn't make any difference. we're go, go myself and seize, and i put onto the whole lake open. i will do a photo so that from that's i only have a state one by the way, so that can in the but that doesn't even leave enough for me to rebut them. doesn't mean the money. i would be michael now. but to us and kenyon scientists have identified a fungus that kills the parasite. it's highly effective, even in tiny amounts, such as might fit on a tooth pick. this discovery led to the tooth pick project dorcas campbell. he manages the projects tooth pick company for a team of scientists produce the fungus that kills to strike a plot. a lindsey within the research on the bile controls and

struggling using say, i'm looks as far as this phone goes as isolated from my wilton's trego. it and h was growing to make them bound control. so initial non is contrary to what we do in this knob. is multiply, the fung us as much as we can, so that is can quantity if i to a must, that's can solve the form of in great capacities for the last 5 years. ken boy has traveled to villages and west in kenya to introduce farmers to the product. it costs about 30 year rose to treat a one acre field. until now farmers have been up routing the destructive plot to prevent its seats from spreading further. because once they're in the soil, they stay there for years. chemical pesticides haven't proved effective and farmers are left with field harvests. that's why the tooth pick project is supported by a number of n g o's focused on food security. daddy's brittany effect of climate change. the

i've is one me before it was a warming, and we a seems dried, got also moving event to some width as owns and to also some for the region is that these experienced in the high production, 80 ascending means the food insecurity also is except it becomes much more kenya isn't the only country with a strike, a problem. according to the u. n, a 14 african nations are infested with the weed. this makes the project all the more important is successful. it could be introduced in other countries to. so dorcas can, boy, is working with ag farm us to help produce more fund going up to them. they can show it to that's can be produced. that's our laboratory, you know, to now, to solve from us i have closed this of in county. so we all find anything and so that is the reason why we were in gauging village, you know, clump produced stuff and they really never opened had class pretty put the final

product production itself is relatively straightforward. the phone goes just needs to grow 20 key. those of rice are cooked and a small amount of fungus is added, then left for $3.00 to $5.00 days to incubate. the resulting for to key low as a function, rich dries are enough for one, a couple of crop land. the research has found at that farm as needed to treat the fields for 2 years. that's full crops, owings that was enough to banish the strike. and restore crop yields for small hold is especially, it's a relatively easy remedy that the farmers can apply for themselves. was really interesting, so listen up. i've been beaten by these annoying lead to box way so many times in my life you to full of late. but auction most controls can also be good willing to box. yes. you have right here, a small they are believed to have killed alexander the great and they help the us.

when independents from the british mosquitoes have shape the human history. they are the world's deadliest animal, the viruses and power sites. they carry still kill hundreds of thousands of people every single year. that's why scientists are developing technology that could completely wipe out certain mosquito species. but critics argue their extinction could just be the beginning. that other species could follow destabilizing entire eco systems. so just because we could kill off an entire speech, these should we mosquitoes kill more people every year than all other animals combined. some 700000 annually. and it's actually the parasites and viruses hitching a ride from the yellow fever and west nile to the most deadly. larry has been that the, the killer, you know,

across our existence from, from our home and ancestral evolution all the way to present data. unfortunately, malaria is responsible for around 80 percent of mosquito related deaths. and almost all of those are children under the age of 5, mostly living in africa, the majority of mosquitoes don't carry this lethal parasite. most of the more than 3500 different types are in fact harmless. own the anomalies mosquitoes can carry malaria. nowadays, the disease is transmitted predominantly in tropical and sub tropical parts of the world for more than a century. now, scientists have been trying to come up with ways of destroying the anomalies mosquito live besides insect decides they've had varying degrees of success. so over the last 2 decades, scientists of turn to a new method of reducing mosquito numbers, genetic modification, the ability to trust with disease, a nice and influence by him. i'm

a member of the genetic traits which are available today to link them them like you might be able to. ready developers, people do enough trust me to malaria. andrea chris sante and his team are genetically modifying and also these can be a mosquitoes. the species that transmit civil area in africa. only female mosquitoes are able to bite humans and transmit malaria. the needs of proteins in our blood to make eggs. we focus on jewels that are able to compare and we'll scale that we were able to manipulate these genes and generate the list of mosquito. have mail traits into a lot by edits a gene they used to. chris berg, a relatively new technology that is used to modify dna. as a result, even the female aux spring of the modified mosquito were born with mouth parts that could not peer skin rendering them unable to feed from blood. it also made them

scenario. additionally, the scientists use the gene, dr. it increases the odds of the modified gene being passed on to offspring. these 2 methods, genetic manipulation and gene drive lead to the complete collapse of the test population within a year. so that was in test conditions. if released into the wild beast, genetically altered mosquitoes have the potential to drive the and off of these can be a species to extinction. and vent would drastically reduce some of the larry a transmission. the scientists believe the modification would not necessarily reach all areas where the species is found. but containment of living animals isn't always so easy. take so wrapped, as humans began to travel, the high seas wrote in species stowed away on ships. they ended up over whelming island donations gene. dr. opponents argue that like invasive species,

genetically altered mosquitoes would migrate. it's really a concern that these organisms to spread uncontrollably and possibly crush populations, or possibly lead to extensions of space is designed to spread aggressively throughout the spaces and also to spread geographically across the board. is the point is how, what's the potential extinction of the anomalies cambia mosquito impact ecosystems? just like b as in butterflies, many mosquitoes b, she's are pollinators transferring pollen from flower to flower. so what would the disappearance of the enough of these mean for plants? and what about the fix birds and baths that feed on mosquitoes? then there is the genetic alteration itself. there is the possibility of it being passed on to other species of mosquito putting them at risk when you decide what risk were willing to take it or do something like save the environment or in the case of malaria,

dr. save human lines. wiping out species that cause death and destruction may sound positive, but once they are gone, what next? where do we draw the line? are using a technology that's, you know, instruments lies the extinction as a total. that's a new special human being. so it's not crossed before. so mosquitoes could be at the center of another major shifting human history. we need to play that careful line of like really thinking through the 1st use of these things and what that will look like, how the account and take reasonable risks. but as scientists still don't know so much about the potential consequences of unleashing animals with a genetically modified gene drive, it is hard to evaluate those risks. okay, good to know. so to change the topic, did you know that the construction industry is one of the last pulls?

it says, yes, it is true, but it is because so many vol. materials a need is yes. and they have been used to build more and more. just look at the exploding population here in our gerry. yeah. but there are ways to make building green us. you'll see. and this 6 go in your bit. these bugs contained the building materials of the future. green cement that's almost common free. it has the potential to make building much more climate friendly. but for the main problem with traditional cement is the c o 2 emissions of generates producing one ton of traditional cement release is nearly one ton of c o. 2 in the us here in doesn't just to do that mode of 4600000000 tons of cement. i used globally every year and the trend is rising. so the construction

industry is putting a huge bid on the climate. some and production is very energy intensive. that's part of the weight release and so much c o 2. but no manufacture is around the world of developing new processes, including this one from, from district with small for the reason why our cement has much less carbon than traditional cement is the production process that we use typically now there's no gas involved, no firing a raw materials come from recycling because we use industrial waste and thanks to our solar trackers, these were able to generate around 50 percent of our own power and the 2nd semester . the result is a cement with an impressively small carbon footprint. green concrete is being produced by a growing number of companies worldwide, while others are working towards it, creating the foundation for

a little climate from the future. and how about you? if you're also doing your bit, tell us about it, visit our website, or send us a tweet. hash tag doing your bit. we share your story. are back to africa now with the rivers, a lifelines in many parts of the continents. there was a useful both domestic and agriculture of purpose is making a lot of people reliant on the reverse for their livelihoods. but the increased by aggression to urban areas is taking its toll. a john, this bird, the 10 of river is chronically polluted with devastating consequences for biodiversity and communities. living alone gets banks. now local volunteers of working to limit the damage piles of rubbish,

washed up heavy rains. it's a come on site, densely populated areas along the head of the city. of this sport is just a few meters from some piece of township home to more than half a 1000000 people. our children play around here and 530. so just next to the you and then that forty's contact me to is it everyone is getting sick of which is not? yeah, could you please invite them for us now? not face representatives from the south african and your french take stock of the devastation. the mission is to restore the helps river need surrounding wetlands with the help of volunteers just below the source of the river . this is beautiful fountain was is to be present. yes. but if we don't pick up this press, no one's going to pick it up. today, the team from fresh,

once the inspect one of the little traps full has been installed on the reverse of the course. the end you has invented its own traps. they are constructed from thick wire cables woven through nets, unfilled with recycled polystyrene. the construction is on code on either side of the river, mostly cuts as part of funding the floods. and also what's inside of interest to, to slow the water down. so settlements out a lot of santia and that sir, and also serves as to whom. so beneficial organisms, it presents for the erosion to the souls of the hand of 3. but you see 2, we took east of john as for, after leaving the oven areas behind it, manders, through fields and valleys, alternately eventually joins the limpopo river system easily to ends up in the indian ocean. this intricate system of water. we supports millions of people in

both south africa and 3 neighboring countries. this river is an important source of drinking water is also vital for agricultural crops. farmers like you hadn't seen but a very concerned sometimes that of a just totally black because of the cities is very bad. crosby, what it's about the 1st part in the, in the what that go into the ground, go into the crops and i don't think it's healthy for the ground is also not the office of people that smoke or large amounts of raw sewage, just spilling into the head of lots of samples i tested for equal live bacteria to assess the cold contamination. yeah, the river source, the cool i concentration has been measured as a 100000 times above the accepted limit. so fresh is now pushing to get the river landscape officially declared a nature conservation area,

also protected by diversity, colorado meandering through the most urbanized areas on the continent. it would help to revitalize south africa's industrial heartland on earth date, a group from fresh set house to demonstrate to they also reduce the potential of a clean river system. the returns the little trap on the mission to remove 60 tons of weeks from these spots in one d, it is beautiful. the river is leaving things. oh wait. time is looking much better . i think we can we can we store the space. it's a win plant. 80, so if it gets polluted and then in that i'd give you actually go south and swap because we do sort i wouldn't be able to sustain life and sustains. so we depend on the quote to the sort of system this time is lying out. it was really great to have you with us today. it is a good buy from complex,

right to in uganda. i really hope you enjoyed the shell. and by, for me, an idea of, if you want to know more, check out the social media channel shown on your screen. hopefully we'll see you next time by the

social media coming as i'm going is retro active resolution. and so, so we in all of the digital spacers and for pod costs for on wheels

me sell stuff because modern spiritual feelings and find out what the best rate is . all about. the 77 percent the for nearly 4 decades. she has thoughts peacefully for race of freedoms in the wrong nursing suit today. ready children should not inherit science from an income. if you look into how nice the 3 dots to lie, 2900 dw. how does the discovery change your mind?

just click away, find out best document trees on you to see the world, the subscribe. now to dw talking entry, the, the, the,

this is the w news live from, but in russia, blaine's ukraine for an emergency on a bridge linking brush always by mail on verifying voltage from the pro russian. sol shows damage to the bridge of the reports of lost. so be nice and then use that at least 2 people of data.
